Actor Yoo Ah In (37), whose real name is Uhm Hong Sik, is currently facing police summons and investigation for alleged drug use. Recently, he hired a lawyer who is a former prosecutor from a top law firm in South Korea, Kim & Chang.

Yoo Ah In's lawyer worked as a prosecutor for 11 years from 2006, and in December 2017, he joined Kim & Chang Law Firm, but he currently works at a different law firm. This law firm also includes a former chief prosecutor and an attorney who was a drug and organized crime department chief.

The Seoul Metropolitan Police Agency's Narcotics Crime Investigation Division has summoned Yoo Ah In as a suspect for violating the Narcotics Control Act, specifically for narcotics, on March 24 at 10 AM KST. Last month, the National Forensic Service revealed positive reactions for four types of narcotics, including marijuana, propofol, cocaine, and ketamine, in Yoo Ah In's hair and urine.

The police have already searched and seized medical clinics and hospitals in Gangnam and Yongsan-gu in Seoul, where Yoo Ah In is suspected of having been prescribed propofol and other drugs, as well as his residence. They have also called Yoo Ah In's manager and acquaintances as witnesses for questioning on the 13th and 14th of this month.
